Consume items on the map

The functions here consume accessible items / item charges on the map or in vehicles around the player (whose positions is given as origin).

They return a list of copies of the consumed items (with the actually consumed charges in it). The quantity / amount parameter will be reduced by the number of items/charges removed. If all required items could be removed from the map, the quantity/amount will be 0, otherwise it will contain a positive value and the remaining items must be gathered from somewhere else.

Detailed Description

Manage and cache data about a part of the map.

Despite the name, this class isn't actually responsible for managing the map as a whole. For that function, see mapbuffer. Instead, this class loads a part of the mapbuffer into a cache, and adds certain temporary information such as lighting calculations to it.

To understand the following descriptions better, you should also read Map Management

The map coordinates always start at (0, 0) for the top-left and end at (map_width-1, map_height-1) for the bottom-right.

The actual map data is stored in submap instances. These instances are managed by mapbuffer. References to the currently active submaps are stored in map::grid: 0 1 2 3 4 5 6 7 8 In this example, the top-right submap would be at grid[2].

When the player moves between submaps, the whole map is shifted, so that if the player moves one submap to the right, (0, 0) now points to a tile one submap to the right from before

◆ add_vehicle_to_map()

std::unique_ptr< vehicle > map::add_vehicle_to_map ( std::unique_ptr< vehicle veh,

private

Takes a vehicle already created with new and attempts to place it on the map, checking for collisions.

If the vehicle can't be placed, returns NULL, otherwise returns a pointer to the placed vehicle, which may not necessarily be the one passed in (if wreckage is created by fusing cars).

Parameters
vehThe vehicle to place on the map.
merge_wrecksWhether crashed vehicles become part of each other
Returns
The vehicle that was finally placed.

Apply trap effects to the creature, similar to creature_in_field.

If there is no trap at the creatures location, nothing is done. If the creature can avoid the trap, nothing is done as well. Otherwise the trap is triggered.

Parameters
critterCreature that just got trapped
may_avoidIf true, the creature tries to avoid the trap (Creature::avoid_trap). If false, the trap is always triggered.

◆ draw()

void map::draw ( const catacurses::window w,
const tripoint center 
)

Draw a visible part of the map into w.

This method uses g->u.posx()/posy() for visibility calculations, so it can not be used for anything but the player's viewport. Likewise, only g->m and maps with equivalent coordinates can be used, as other maps would have coordinate systems incompatible with g->u.posx()

Parameters
wWindow we are drawing in
centerThe coordinate of the center of the viewport, this can be different from the player coordinate.

◆ load() [1/2]

void map::load ( const tripoint w,

Load submaps into grid.

This might create new submaps if the mapbuffer can not deliver the requested submap (as it does not exist on disc). This must be called before the map can be used at all!

Parameters
wglobal coordinates of the submap at grid[0]. This is in submap coordinates.
update_vehiclesIf true, add vehicles to the vehicle cache.
pump_eventsIf true, handle window events during loading. If you set this to true, do ensure that the map is not accessed before this function returns (for example, UIs that draw the map should be disabled).

◆ move_cost() [1/2]

int map::move_cost ( const tripoint p,

Calculate the cost to move past the tile at p.

The move cost is determined by various obstacles, such as terrain, vehicles and furniture.

Note
Movement costs for players and zombies both use this function.
Returns
The return value is interpreted as follows:
Move Cost Meaning
0 Impassable. Use passable/impassable to check for this.
n > 0 x*n turns to move past this

Place items from item group in the rectangle f - t.

Several items may be spawned on different places. Several items may spawn at once (at one place) when the item group says so (uses item_group::items_from which may return several items at once).

Parameters
locCurrent location of items to be placed
chanceChance for more items. A chance of 100 creates 1 item all the time, otherwise it's the chance that more items will be created (place items until the random roll with that chance fails). The chance is used for the first item as well, so it may not spawn an item at all. Values <= 0 or > 100 are invalid.
p1One corner of rectangle in which to spawn items
p2Second corner of rectangle in which to spawn items
ongrassIf false the items won't spawn on flat terrain (grass, floor, ...).
turnThe birthday that the created items shall have.
magazinepercentage chance item will contain the default magazine
ammopercentage chance item will be filled with default ammo
Returns

◆ save()

void map::save ( )

Add currently loaded submaps (in grid) to the mapbuffer.

They will than be stored by that class and can be loaded from that class. This can be called several times, the mapbuffer takes care of adding the same submap several times. It should only be called after the map has been loaded. Submaps that have been loaded from the mapbuffer (and not generated) are already stored in the mapbuffer. TODO: determine if this is really needed? Submaps are already in the mapbuffer if they have been loaded from disc and the are added by map::generate, too. So when do they not appear in the mapbuffer?

That is, if the tiles are adjacent and either on the same z-level or connected by stairs or (in case of flying monsters) open air with no floors.

◆ vertical_shift()

void map::vertical_shift ( int  newz)

Moves the map vertically to (not by!) newz.

Does not actually shift anything, only forces cache updates. In the future, it will either actually shift the map or it will get removed after 3D migration is complete.

◆ abs_sub

tripoint map::abs_sub

Absolute coordinates of first submap (get_submap_at(0,0)) This is in submap coordinates (see overmapbuffer for explanation).

It is set upon:

  • loading submap at grid[0],
  • generating submaps (generate)
  • shifting the map with shift
